This paper reports the results obtained during the investigation of the emission spectra of Eu3+:Ca3Ln(=Y,Gd)(VO4)3 phosphors that are prepared by a chemical co-precipitation method. For these phosphors, XRD, SEM and FTIR analysis have also been carried out to understand their structural properties. When these Eu3+ phosphors were put under an UV source, those were in bright red luminescent. Based on the red color emission richness and also emission spectral measurements, Eu3+:Ca3Y(VO4)3 phosphor has been found to be a better material compared with Eu3+:Ca3Gd(VO4)3 phosphor. An energy level scheme has been presented to explain the emission process involved in these phosphors.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
